Tiger shark facts, habitat and behaviour
The tiger shark is one of the ocean’s most powerful predators, known for its tiger-like stripes, fearless nature and for being the 'the garbage can of the sea'.
Found in tropical and temperate seas, this large shark can grow to over five metres long and is famous among divers for its strength, curiosity, and unmistakable beauty.

What is a tiger shark and why is it called that?
The tiger shark is a large, fearsome species named for the dark, tiger-like stripes that run along its flanks when young.
These markings fade as the shark matures, but can still be seen as an adult shark and its bold reputation remains.
Found in warm waters around the world, the tiger shark is second only to the great white in size among predatory sharks. Its scientific name, Galeocerdo cuvier, hints at its power and agility, making it a true marvel of the marine world.
Where do tiger sharks live?
Tiger sharks prefer tropical and subtropical seas, roaming the waters off Hawaii, the Caribbean, the Maldives, and the Red Sea.
They are often found near reefs, continental shelves, and even in deep open water. Because tiger sharks are highly migratory, divers may encounter them in many different parts of the world, especially in regions rich in marine life and turtles, such as the Bahamas or Fiji.
Their wide distribution makes them one of the most studied large shark species.
What do tiger sharks eat?
The tiger shark’s diet is incredibly varied, earning it the nickname “the garbage can of the sea.”
Tiger sharks feeds on fish, turtles, seabirds, and even smaller sharks. This adaptability helps them survive in changing environments.
Whilst the tiger shark’s feeding habits are sometimes sensationalised, in reality, it plays a vital role in keeping marine ecosystems balanced by removing weak or sick animals from the food chain.
How big can tiger sharks grow?
Adult tiger sharks typically reach lengths of 3 to 4.5 metres, but some feamle individuals have exceeded 5 metres and weigh more than 600 kilograms.
Despite their size, tier sharks are graceful swimmers with an unmistakable silhouette, a broad head, powerful tail, and blunt snout. Like all sharks, they have a streamlined body which allows them to move efficiently through the water, conserving energy while hunting or travelling long distances.
Are tiger sharks dangerous to humans?
Tiger sharks are powerful predators and should be respected, but tiger sharks are not naturally aggressive towards humans.
Most encounters occur when a tiger shark mistakes a person for prey or when they investigate out of curiosity. This can happen with a surfer, who from the tiger shark's perspective might resemble a turtle below the surface.
Responsible shark diving operations around the world allow people to observe tiger sharks safely at dive sites like Tiger Beach, providing thrilling yet controlled experiences that promote conservation and a better understanding of these incredible creatures.
Why are tiger sharks important to the ocean?
As apex predators, tiger sharks help maintain balance in marine ecosystems. By controlling prey populations and preventing overgrowth of certain species, they keep coral reefs and ocean habitats healthy.
Scientists also study tiger sharks to learn about migration patterns, climate impacts, and oceanic food webs, making them an essential part of marine research.
